There are the detecting instrument of function of shielding, the quality of performance indicator to play a crucial role the research and development and production of product, only
Cuspidated detecting instrument could help us to develop the product at tip.Ideal test darkroom needs to include following portion
Point：1. darkroom shields main body：Its shielding properties should meet test request, while reduce occupied space to greatest extent again；②
Accurate mounting seat：Left and right precision instrument and equipment is required for directly or indirectly being fixed in mounting seat in darkroom,
Therefore the precision of pedestal is the basis of equipment overall performance guarantee；3. automatic loading/unloading platform：It is required that it has early X-Y-Z tri-
Dimension carries out automatic lifting, the function of auto-translating, convenient for test antenna disengaging darkroom and be automatically performed different height flat bed
It is required that；It is also required to meet the requests for alternations with production line assembly, realization automatic on-line detection simultaneously；4. automatically scanning
Frame：During antenna measurement, need to carry out receiving and transmitting signal acquisition to the electromagnetic wave of antenna by the probe on sweep mechanism, and anti-
Background test system software of feeding is analyzed；The required precision of scanning support is very high, and one is that flatness wants high (every square of rice and flour
Product≤0.03mm), second be that precisely (≤0.03mm), third are that control response speed will fast (≤3ms) for displacement.
The test darkroom designed in instrument market at present also substantially has above several component parts, but different because being related to
Profession is responsible for processing so being all respective independent design by different production firms, then carries out on-site consolidation by user,
It can have the following defects in this way：1. making overall planning, design level is relatively low, and Design of Mechanical Structure is difficult to seek unity of standard, compatible support
It is difficult to optimize, overall performance is influenced after assembling；2. being not easy to reach Miniaturization Design target, occupied space is larger, is unfavorable for testing
It is used on room and assembly line；3. automatization level is relatively low, especially loading and unloading need artificial lift to put, and inefficiency is again uneasy
Entirely；4. assembly and adjustment is complicated, time-consuming longer, efficiency is low；And it is related to multiple suppliers, there are quality problems, responsibility is also difficult to draw
Point；5. stability is poor, need to debug correction again later using a period of time；6. current same category of device is mostly to meet laboratory
Research and development use, and cannot be satisfied the use of assembly line on-line checking；7. there are quality problems, it is difficult to which decision problem root causes to call to account
It is difficult；8. after-sales service is inconvenient, the same different component of equipment is broken and needs to look for different suppliers.
